Thanks for the update. I did indeed see that picture earlier, so I will do that!

Have you tried and liked any other LEDs in this light, or do you just stick with de-doming the original XM-L2?

My mod thusfar was always with dedomed XP-G2, the right one, together with ‘streamlining’ the current path, gave just over 50 kcd.
(here I wrote about the mod)

djozz, I definitely read that thread and got good info from it. My plan with this light is actually to sell a few to coworkers, and the criteria here at work would either be higher overall lumen output, or high CRI, moreso than maximum throw.

My thought was basically two different lights they could pick from:
1) High output: XM-L2 U4 1A (dedomed if they really want more throw), or
2) Nichia (various types, I bought a variety in clemence’s GB).

I can’t imagine why a Nichia would not work OK, but I figured I’d ask.

I might build a de-domed XP-G2 for myself though. Thumbs Up

If you try a nichia let’s us know. I’m curious if it will allow for more current because of the low vf or if it is already maxed for current, the output might be noticeably less that xpg2 xml2. XPL hi is an option as well. I really like the 3D tint. It gives less throw than xpg2 and dedomed xml2 but the factory dedome has some silicone to protect the phosphor and may add some reliability. Any selection will give you a nice light though:)

Well it’s an e-switch, so modes are hi-med-lo-strobe-sos, always starts on hi. No mode memory, 1st click from OFF goes to hi, them click-med, click-lo, click-strobe, click-sos, click-hi. To turn it OFF, press&hold. I took detailed pics, took output measurements, amp readings, etc. Got it fully dis-assembled – pretty quick, pretty easy (no glue, all std CCW to loosen)


On a fresh Samsung 30Q: 2.15A tail on hi (DMM meter, heavy wires)



  • For zoomed in (flood), lumens hi: 690 start, 653 30 secs, med: 350, lo: 139

  • Throw in full zoomed out focus: 11 kcd taken 5 meters</li> <li>Body length: 126.8 mm -&gt; 138.8 mm</li> <li>Parasitic drain: <strong>0.016 mA</strong> (very low, 7+ years to drain 1 Ah)</li> <li>If I jumper the tail, and measure lumens: <strong>731 start (this means you probably get a 5%-6% bump if you bypass the tail spring)


It’s almost there, but I’d have to say the modes are a great disappointment, but as advertised. Shame because doing modes better adds nothing to the manufacturing costs, only a bit more up front software dev, non recurring costs. Pics being uploaded…

Would low last 10 hrs?

Moved recently and found the A2 I purchased from Tom E. Just wondering about the runtime, planning to do a camping trip with my family and friends. LOL
